What I liked about it are simpler to understand if you ever lived in a sunny and mostly hot area before. The sun and heat do their best to destroy anything tech, especially if they're plastic based. Electronics that are outdoors don't fare well in the long term and will eventually breakdown after a limited life unless protected properly. The Pentair system does something that no other salt cell company does. They put the needed electronics on the cell rather than a separate power station so when the cell is replaced every year you also get new electronics that monitor the system with no loss of quality. The sad part is that the system is comparable in cost with other cell systems that require separate controls that suffer from heat, sun, and age over time.
This system is used for about a year and is replaced when the cell is replaced basically giving you a brand new system every time you replace the cell.
